MFC r256870, r256898, r256899, r256900 (by nwhitehorn):
Standards-conformance and code deduplication:
- Use bus reference phandles in place of FDT offsets as IRQ domain keys
- Unify the identical macio/fdt/mambo OpenPIC drivers into one
- Be more forgiving (following ePAPR) about what we need from the device
tree to identify an OpenPIC
- Correctly map all IRQs into an interrupt domain
- Set IRQ_*_CONFORM for interrupts on an unknown PIC type instead of
failing attachment for that device.
Allow lots of interrupts (useful on multi-domain platforms) and do not
set device_quiet() on all devices attached under nexus(4).
